Manufacturer:APEX Cirrus Logic Description:As shown in Figure 2, the DSPs two internal memory blocks populate all of Page 0. The entire DSP memory map consists of 256 pages (Pages 0−255), and each page is 64K words long. External memory space consists of four memory banks (banks 0C3) and supports a wide variety of SRAM memory devices. Each bank is selectable using the memory select pins (MS3C0) and has configurable page boundaries, waitstates, and waitstate modes. The 1K word of on-chip boot-ROM populates the top of Page 255 while the remaining 254 pages are addressable off-chip. I/O memory pages differ from external memory pages in that I/O pages are 1K word long, and the external I/O pages have their own select pin (IOMS). Pages 0C7 of I/O memory space reside on-chip and contain the configuration registers for the peripher- als. Both the core and DMA-capable peripherals can access the DSPs entire memory map. |
